Zusammenfassung:	The disclosure belongs to the technical field of biochemical engineering, and particularly relates to an extraction method for polysaccharide in plants. The extraction method comprises the following steps: enzymatically hydrolyzing plant raw materials to obtain enzymatic hydrolysate; sequentially mixing the enzymatic hydrolysate with an inorganic salt aqueous solution and an organic solvent, and performing two-phase salting-out extraction on the obtained mixed liquid to obtain alcohol-soluble polysaccharide and water-soluble polysaccharide. The alcohol-soluble polysaccharide can be synchronously separated and obtained while the water-soluble polysaccharide is efficiently extracted. Meanwhile, the method has moderate operating conditions, is easy and convenient to operate, low in equipment requirement and high in applicability, and facilitates large-scale industrial production.
